That’s how quite expensive for prime 12mm m.Zuiko can’t match 12-60mm Zuiko in sharpness despite of the later having optically lot more demanding 5x zoom range with additional challenge of being very heavily retrofocal at 12mm.

Adding few more parameters into data told by lens to body doesn’t cost any to manufacture unlike more complex optics so that should at least show in price!

A fast ultra wide, like 100 degree angle of view please. And hopefully if they are going to bring out something with a higher spec than the EM5 they are already talking to Nauticam so that there will be a housing for it. I wonder if they have thought of a RAW video out….?

The later isn’t just needed for quickly adjusting focus, but also as a strong indicator that something moved between the subject and the camera. Current m4/3 C-AF implementations cannot deal with that properly (tho the E-M5 with the 12-50 does try, but you have to help it by pressing a button when something moves between the camera and subject).

Currently PDAF is the only practical way of doing that, but in theory it is also possible to do this with chromatic defocus (making use of the fact that different wavelengths are refracted slightly differently, a trick nature also uses for some animals that need to very accurately judge distances). The problem with chromatic defocus is that it heavily depends on the specific lens being used, and is incompatible with some highly corrected lens designs.
